Wildflower Collection

Wildflower Collection

  • NEW in 2013
  • Help boost bee and butterfly numbers
  • Easy to grow

Establishing your own wildflower meadow couldn’t be easier with this diverse collection of wildflower plug plants. A wildflower patch in your garden makes a lovely informal display that needs little maintenance. You'll be amazed at the beneficial insects and birds they attract, many of which will act as pollinators and natural pest control for your garden! Try sprinkling some wildflower seed between these plug plants - they will all knit nicely together. The perennial varieties will come back year after year whilst the annuals will happily self seed and reappear in a new position each year. Height: 150cm (59"). Spread: 50cm (20").
